Re: [xcat-user] sequential discovery issue

Fri, 17 May 2013 07:51:19 -0700

Hi Xiao,

I appreciate your answers,

When I first started using xCAT, we used to do exactly this where we had the BMC of nodes in the nodelist table as well, and also assign them into hosts.ip, since the arrival of otherinterfaces in the hosts table, we didn't see the need for this, as the otherinterfaces was sufficient to do what we needed it to do, plus we can easily see with an lsdef of a node, and see what is related in terms of IPs.

Are we now saying we go back to the old method in order for sequential discovery to work, i.e. I need to do the following commands

nodeadd node001-node004 groups=compute
nodeadd node001-bmc-node004-bmc groups=nodebmc
chtab node="compute" hosts.ip="|\D+(\d+)|10.0.0.(\$1*1)|"
chtab node="nodebmc" hosts.ip="|\D+(\d+)-bmc|10.0.1.(\$1*1)|"

instead of

nodeadd node001-node004 groups=compute
chtab node="compute" hosts.ip="|\D+(\d+)|10.0.0.(\$1*1)|"  hosts.otherinterfaces="|(\D+(\d+))|(\$1)-bmc:10.0.1.(\$2*1)|"

I would like to get feedback from other customers and providers on how they would do this?

Arif,

    Several points to clarify:

    1. hosts.otherinterfaces will be deprecated for outside using. That means the definition of second interfaces for host will not use hosts.otherinterfaces. But xCAT still uses it inside. Additionally, the hosts table is still been using.
    2. Mostly, the nics table should be used to configure the second interfaces (that means not include the primary interface). Maybe someday later, xCAT will support it completely. Even xCAT could support it, the code logic is complicated.
    3. Presently, the primary IP of host and BMC should be put in host.ip.
    4. Setting the IP of host (primary interface) and IP of BMC in the host.ip is necessary for sequential discovery.
 
Thanks
Best Regards

Xiao,

So from the docs et al, the otherinterfaces will be deprecated, so started to use nics table since 2.8.

As part of the otherinterfaces in the hosts table allows me to automatically create the hosts file, without having to do it manually, or adding the nodes individually into the nodelist table. i.e. assign the ip to the node, so that it is not cluttered.

In the same way, I grasped the idea to do the same thing with the nics table, to not necessarily create the interface on the nodes itself, but to automaticllay create the hosts table, and hence the named configuration

I would expect though that the discovery method to lookup a specific value from the ipmi table, and cross check with the nics tables to see what the IP address and and use that as part of the discovery process. correct me if my assumption here on how it should work is wrong.

regards,
Arif

    Arif,

      The nics table only can be used to configure the host, but can NOT set the bmc. If you set the attribute nicips.bmc, that means you should have interface named 'bmc' in the host, so that during the boot up of the node, confignics postscript will configure the interface 'bmc' base on the attribute values.
    Guang Cheng,
      Please correct me for the usage of nics table.

    Hi Xiao,

    If you look at the lsdef, you will see that I have set the IP address of the bmc, or does the type need to be different?

    # lsdef node001 | grep bmc
     nichostnamesuffixes.bmc=-bmc
     nicips.bmc=10.0.1.1
     nicnetworks.bmc=xcat_nw

      Arif,       

        I think the problem was you did not assign IP for the bmc. The ip you set the in nics table only for the host. If you add the entry in the hosts table for the ip of bmc, it would work.

      Hi team,

      I am trying to get the sequential discovery working on a 4 node cluster, and I am struggling to get passed the following error message, and trying to understand where I am going wrong

      May 15 15:46:09 mgmt1 xCAT: xcatd: Processing discovery request from 10.0.0.101
      May 15 15:46:09 mgmt1 xCAT: Sequential Discovery: Processing
      May 15 15:46:10 mgmt1 xCAT: Sequential Discovery: Auto Stopped because all bmc ips in the specified range have been assigned to discovered nodes. Run 'nodediscoverls -t seq' to display the discovery result.

      I started the discover by running the following command

      # nodediscoverstart noderange=node00[1-4]

      Below is my definition of the node itself.

      # lsdef node001
      Object name: node001
       bmc=node001-bmc
       chain=runcmd=bmcsetup,shell
       cons=ipmi
       groups=compute,ipmi
       ip=10.0.0.1
       mgt=ipmi
       netboot=xnba
       nichostnamesuffixes.bmc=-bmc
       nichostnamesuffixes.ib0=-ib0
       nicips.bmc=10.0.1.1
       nicips.ib0=10.0.2.1
       nicnetworks.bmc=xcat_nw
       nicnetworks.ib0=xcat_ib
       nictypes.bmc=ipmi
       nictypes.ib0=infiniband
       _ondiscover_=nodediscover
       postbootscripts=otherpkgs
       postscripts=syslog,remoteshell,syncfiles
       power=ipmi
       serialport=0
       serialspeed=19200

      I would expect xCAT to grab the IP from the defined IPs in the nics table, and assign this IP.

      I have then since realised, the following command works

      # nodediscoverstart noderange=node00[1-4] groups=compute,ipmi bmciprange=10.0.1.1-10.0.1.4

      Which is I think inefficient, especially everything is already defined in the xCAT database
